Discharge Mode; Refresh Mode; Test Mode - La Crosse Technology Battery Charger Instruction Manual

batteries drops to a safe level. If overheat conditions continue to occur, the
rechargeable batteries shall be taken out to cool down and then charged at a lower
current.
For a new rechargeable battery it is recommended to charge it with 200 mA current
for re-conditioning it from the long storage status.

DISCHARGE MODE

Discharge mode will first discharge the rechargeable battery then charge it. It is for removing
the memory effects of rechargeable batteries.
By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the
Discharge mode can be selected. (The mode key shall first be pressed and held for about 1
second to activate the mode change. The subsequent pressing of the mode key will enable
to toggle between the "Charge", "Discharge", "Test" and "Refresh" mode.)
Finally batteries will be fully charged in discharge mode and "Full" will be displayed. If user
presses DISPLAY key at this time, "charge" icon instead of "discharge" icon will be displayed.

REFRESH MODE

Old rechargeable batteries and those have not been used for a long time require refreshing.
This process will recover the optimum capacity of the rechargeable batteries. By pressing
the MODE key within 8 seconds after inserting the rechargeable batteries, the Refresh mode
can be selected.
Refresh mode will start with discharging the rechargeable battery, then charging it. The
repeated discharging and charging cycles will be launched until no further increase in the
measured capacities is estimated.
When the battery is overheated the charging
ceases automatically. "000 mA" will be
displayed.

Then user may also select a different discharging current (see Table 2) by pressing the
CURRENT key, within 8 seconds after inserting the batteries. (The display will blink once to
indicate the setting has been confirmed and the current cannot be changed afterward.)
Note: The discharging current is always set to be half of the coming charging current
whose upper limit is 700 mA (see Table 2). Therefore user is recommended to carefully
select the discharging current so that the charging current afterward will not be too high.

Note:
By pressing the MODE key within 8 seconds after inserting the rechargeable
batteries, the Refresh mode can be selected. (The mode key shall first be pressed
and held for about 5 seconds to activate the mode change. The subsequent pressing
of the mode key will enable to toggle between the "Charge", "Discharge", "Test" and
"Refresh" mode.)
Then user may also select a different discharging current by pressing the CURRENT
key (see "Note" in Discharge mode and Table 2), within 8 seconds after inserting the
batteries. (Or the display will blink once to indicate the end of setting and the current
cannot be changed afterward.)
It may take up to several days to finish the refreshing process, depending on the
selected discharging current.
The maximum refresh current is 350 mA.

TEST MODE

In Test mode the rechargeable batteries will first be fully charged and then discharged to
determine the capacities. Finally, the rechargeable batteries are charged up again and the
capacity in (mAh) of (Ah) will be estimated and shown after the discharging ends.
By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the
Test mode can be selected. (The mode key shall first be pressed and held for about 5
